    Ramashidzha, Tshifhiwa Marius (University of the Western Cape, 2006)
    The odd – odd Tl nuclei with A ≥ 190 have moderate oblate nuclear deformation and show rotational bands built on different quasiparticle excitations. Several phenomena, not yet fully understood, were observed in these ...
  • Gas sensing properties of Ceo2 nanostructures 

    Khunou, Ramotseng (University of the Western Cape, 2020)
    The industrial safety requirements and environmental pollution have created a high demand to develop gas sensors to monitor combustible and toxic gases. As per specifications of World Health Organization (WHO) and Occupational ...
  • Giant Magnetocaloric effect and Magnetic Properties of selected Rare-Earth compounds 

    Mbulunge, Masevhe Hamisi (University of the Western Cape, 2021)
    Rare-earth (RE) compounds have been an attractive subject, based on the unique electronic structures of the rare-earth elements. In particular, the RETX (RE = rare-earth, T = 3d/4d/5d, transition metals, and X = p – block ...
  • Growth and characterization of FeSi nanowires by chemical vapor deposition for gas sensing applications 

    Thabethe, Sibongiseni Stanley (University of the Western Cape, 2014)
    FeSi nanowires were synthesized via a chemical vapor deposition method. Anhydrous FeCl3 powder in this case served as the Fe source and was evaporated at a temperature of 1100oC to interact with silicon substrates which ...
  • An hi study of the nearby dwarf galaxy ic 4710 

    Mothogoane, Getrude Thando (University of Western Cape, 2021)
    This work aims to study the dark matter content of the nearby (7.38 Mpc) dwarf galaxy IC 4710 using the HI line observations from the Australia Telescope Compact Array (ATCA). We produce the rst interferometric maps of ...
  • High resolution gamma-spectroscopy of environmental samples 

    Rapetsoa, Metsi Monnicca (University of the Western Cape, 2019)
    In this study, a comparison has been made between the available commercial software package Genie 2000 developed by Canberra and Virtual Gamma Spectroscopy Laboratory (VGSL) developed by the Radionuclide Development Unit ...
  • Hot-wire chemical vapor deposition of silicon nitride thin films 

    Adams, Abdulghaaliq (2013)
    Amorphous silicon nitride (a-SiN:H) thin films has a multitude of applications, stemming from the tunability of the material properties. Plasma enhanced chemical vapour deposition (PECVD) is the industrial workhorse for ...
  • Hot-wire chemical vapour deposition of carbon Nanotubes 

    Cummings, Franscious Riccardo (University of the Western Cape, 2006)
